IPFLY Review: SOCKS5 UDP Proxy Tests, Pricing & Features

Description

IPFLY is a proxy service offering residential, static ISP, and datacenter proxies for a range of use cases, from browser profile management to automation and data collection.

According to IPFLY, its residential proxy network includes more than 90 million IP addresses across over 190 countries and regions. Residential proxies support geo-targeting, IP rotation, and sticky sessions, while static ISP or Datacenter proxies can be used for tasks that require a consistent IP address.

The service supports HTTP, HTTPS, and SOCKS5, while one of its more notable technical features is the claimed support for UDP over SOCKS5. In this review, we will go beyond describing IPFLY’s features and test UDP traffic transmission in practice.

For use with antidetect browsers, IPFLY provides standard proxy configuration using the server address, port, username, and password, as well as its own integration guides for AdsPower, DICloak, BitBrowser, and other software. We also tested IPFLY proxies with Afina, Dolphin Anty, GeeLark, and Vision.

Below, we will examine IPFLY’s proxy types, IP management features, integrations, data export options, and the results of our SOCKS5 UDP testing.

IPFLY Services

IPFLY offers three main types of proxy services: Residential proxies; Static ISP proxies; Datacenter proxies.

Residential Proxies

IPFLY’s residential proxies route requests through IP addresses assigned to regular home internet users across various countries and regions. According to the provider, its residential network covers over 190 countries and regions with a pool exceeding 90 million IPs. Users can target IPs by country, region, city, and ASN. For tasks requiring a consistent IP over a given period, sticky sessions are available.

Residential proxies are suitable for:

• Web scraping and data collection;
• Price and website monitoring;
• Checking localized search results and geo-restricted content;
• Automated HTTP requests;
• Working with target sites sensitive to datacenter IP ranges.

When choosing residential proxies, keep in mind that the total network size does not guarantee equal coverage across all locations. If your workflow requires specific geography, it is best to verify availability for that location in advance.

Static ISP Proxies

Static ISP proxies combine a permanent, dedicated IP address with real consumer ISP ASN infrastructure. IPFLY offers dedicated IPs in this category featuring real ISP ASNs, HTTP(S) and SOCKS5 protocol support, and unlimited traffic. Unlike rotating residential proxies, a static ISP IP remains constant across sessions. This makes ISP proxies ideal for long-term IP retention needs.

Typical use cases include dedicated profiles in antidetect browsers and other tasks where frequent network environment changes are undesirable.

Datacenter Proxies

Datacenter proxies utilize IP addresses assigned to data centers. IPFLY provides dedicated static datacenter IPs with support for HTTP, HTTPS, and SOCKS5.

This category also comes with unmetered bandwidth.

Datacenter proxies are best suited for tasks like high-volume automation, continuous monitoring, and querying target platforms that accept datacenter IP ranges.

Pricing and Promo Code

At the time of review, IPFLY lists the following starting prices on its website:

Note that these are strictly base rates. The final cost depends on the selected package size, total IP volume, bandwidth limits, and other rental terms.

For ISP and Datacenter plans, the main pricing section lists the cost per IP without clearly specifying the rental duration. Therefore, these figures should not be assumed as monthly rates per IP without checking the parameters of a specific plan.

IPFLY supports several payment methods, including PayPal, Visa, and USDT.

Advantages

One of IPFLY’s main strengths is combining multiple proxy types within a single platform. Users can easily switch between a large rotating residential pool and static ISP or Datacenter IPs, depending on their specific requirements.

Key advantages include:

• Over 90 million residential IPs (according to IPFLY data);
• Coverage spanning 190+ countries and regions;
• Precise geo-targeting by country, region, and city;
• ASN targeting;
• Sticky session support;
• Dedicated static ISP proxies;
• Dedicated datacenter IPs;
• Support for HTTP, HTTPS, and SOCKS5 protocols;
• SOCKS5 with UDP support;
• Integration guides for major antidetect browsers;
• Multiple payment options: PayPal, credit cards, and USDT.

Having access to residential, ISP, and datacenter proxies in one place makes it easy to handle diverse project workflows without juggling multiple service providers.

Testing SOCKS5 UDP Support

IPFLY’s support for UDP over SOCKS5 deserves a closer look.

Simply having SOCKS5 support does not automatically mean a proxy can forward UDP traffic. Many proxy servers implement SOCKS5 solely for TCP connections.

IPFLY explicitly claims UDP support. In particular, the provider mentions it directly in its documentation when describing proxy usage for Telegram, including voice and video calls.

Technically, the SOCKS5 protocol includes the UDP ASSOCIATE command, which allows a client to send UDP datagrams through a proxy server. This functionality is essential for apps and protocols relying on UDP, such as VoIP and certain messenger features.

However, UDP support must be implemented on both sides: by the IPFLY proxy itself and by the client software you use. If an application only routes TCP traffic through SOCKS5, proxy-level UDP support will not change that behavior.

A standard browser-based IP check cannot verify UDP performance—it only confirms that a TCP connection was established through the proxy.

To go beyond IPFLY’s official claims, we tested UDP support independently. We wrote a custom PHP script that establishes a SOCKS5 connection, executes the UDP ASSOCIATE command, and sends a real DNS query to 1.1.1.1:53 through the returned UDP relay.

This test verifies not just whether the proxy formally accepts the UDP ASSOCIATE command, but whether actual UDP traffic is routed through SOCKS5.

You can use this script to test other proxy providers as well—simply replace the hostname, port, username, and password.

$proxy = "accel.ipflygates.com";
$port = 5001;
$user = "USERNAME";
$pass = "PASSWORD";

function readExact($s, $n) {
$data = "";
while (strlen($data) < $n) {
$part = fread($s, $n - strlen($data));
if ($part === false || $part === "") {
throw new Exception("Incomplete TCP response or timeout");
}
$data .= $part;
}
return $data;
}

function readAddress($s, $type) {
switch ($type) {
case 1: return inet_ntop(readExact($s, 4));
case 3: return readExact($s, ord(readExact($s, 1)));
case 4: return inet_ntop(readExact($s, 16));
default: throw new Exception("Unknown address type");
}
}

try {
$tcp = @stream_socket_client("tcp://$proxy:$port", $errno, $errstr, 5);
if (!$tcp) throw new Exception("TCP: $errstr");
stream_set_timeout($tcp, 5);

fwrite($tcp, "\x05\x01\x02");
if (readExact($tcp, 2) !== "\x05\x02") {
throw new Exception("Server did not select username/password authentication");
}
fwrite($tcp, "\x01".chr(strlen($user)).$user.chr(strlen($pass)).$pass);
if (readExact($tcp, 2) !== "\x01\x00") {
throw new Exception("Authentication failed");
}

fwrite($tcp, "\x05\x03\x00\x01".str_repeat("\x00", 6));
$h = readExact($tcp, 4);
if ($h[0] !== "\x05" || $h[2] !== "\x00") {
throw new Exception("Invalid SOCKS5 response");
}
if (ord($h[1]) !== 0) {
throw new Exception("UDP ASSOCIATE: reply code ".ord($h[1]));
}

$relay = readAddress($tcp, ord($h[3]));
$relayPort = unpack("n", readExact($tcp, 2))[1];
if ($relay === "0.0.0.0" || $relay === "::") {
$peer = stream_socket_get_name($tcp, true);
$relay = trim(substr($peer, 0, strrpos($peer, ":")), "[]");
}
if (!$relayPort) throw new Exception("Server returned UDP port zero");

$host = strpos($relay, ":") !== false ? "[$relay]" : $relay;
$udp = @stream_socket_client("udp://$host:$relayPort", $errno, $errstr, 5);
if (!$udp) throw new Exception("UDP: $errstr");
stream_set_timeout($udp, 5);

// DNS A query for example.com sent through the UDP relay to 1.1.1.1:53.
$id = random_bytes(2);
$dns = $id.pack("nnnnn", 0x0100, 1, 0, 0, 0)
. "\x07example\x03com\x00".pack("nn", 1, 1);
$packet = "\x00\x00\x00\x01".inet_pton("1.1.1.1").pack("n", 53).$dns;

fwrite($udp, $packet);
$reply = fread($udp, 4096);
if ($reply === false || strlen($reply) < 4) {
throw new Exception("No UDP response: UDP data transfer not confirmed");
}
if (substr($reply, 0, 3) !== "\x00\x00\x00") {
throw new Exception("Invalid SOCKS5 UDP header or fragmented datagram");
}

$type = ord($reply[3]);
switch ($type) {
case 1: $offset = 10; break;
case 4: $offset = 22; break;
case 3:
if (strlen($reply) < 5) throw new Exception("Response too short");
$offset = 7 + ord($reply[4]);
break;
default: throw new Exception("Unknown UDP address type");
}
$answer = substr($reply, $offset);
if (strlen($answer) < 12 || substr($answer, 0, 2) !== $id || !(ord($answer[2]) & 0x80)) { throw new Exception("No matching DNS response received"); } echo "[OK] UDP is working: DNS response received through SOCKS5.\n"; } catch (Throwable $e) { echo "[FAIL] ".$e->getMessage()."\n";
exit(1);
}
PHP

In our test, the execution completed successfully: [OK] UDP is working: DNS response received through SOCKS5.

This confirms that the tested IPFLY proxy genuinely forwards UDP traffic over SOCKS5: the DNS query successfully traversed the UDP relay, and a valid response was returned through the proxy.

Note that while this test verifies functional UDP routing, it does not measure connection quality for real-time applications like VoIP or video calling. Evaluating call performance requires separate benchmarks for latency, jitter, packet loss, and connection stability.
